A prevailing theory of mathematical problem solving predicts that children will be less accurate solving a + b = c + __ problems versus a + b = __ + c. However, this has never been tested directly. Because of low base rates, information combined from multiple studies can help improve estimation accuracy and precision. This study compared…

Temperament and attachment, as defined by Bowlby and his followers, are fundamentally different constructs, and research guided by the attachment perspective cannot meaningfully be assimilated to the temperament construct. Qualitative aspects of relationships simply cannot be reduced to individual behavioral dimensions. (RH)

Addresses three questions: (1) To what extent do risk factors of prematurity and illness affect neonatal characteristics? (2) Do these risk factors continue to account for differences in mother and infant social interactive behavior at three months? and (three) To what degree are neonatal characteristics predictive of mother and infant behavior at…

Using extensive, multifaceted observational and interview data from the Family Socialization and Developmental Competence Project (FSP), this paper examines the claims that androgynes, by comparison with sex-typed individuals, are more effective persons and parents. (Author/RH)

Examines the functioning of toddlers with physical anomalies (but without central nervous system damage) in comparison to premature toddlers (with similar deviant early experience but no deviant physical appearance) and to normal toddlers. Premature and disabled toddlers performed more poorly than normal toddlers in measures of social initiative,…
